Fix catalog zone reconfiguration crash
A named
crash was being observed when commenting out a catalog-zone
configuration option, doing rndc reconfig
, then enabling back the
catalog-zone
option and doing another rndc reconfig
.
This commit makes sure to implement the required cleanup of the
in-memory catalog zone during the first rndc reconfig
, so that
the second rndc reconfig
could find it in an expected state.
Closes #1608 (closed)
